Light-power high-light-stability cable material and preparation method thereof

Abstract

The invention discloses a high-power high-light-stability cable material which is prepared from the following raw materials in parts by weight: 3-5 parts of bisphenol A, 2-3 parts of stearic acid, 30-40 parts of ABS (acrylonitrile-butadiene-styrene) resin, 12-16 parts of polyvinyl chloride resin, 6-8 parts of ABS high rubber powder, 1-2 parts of antioxidant 1035, 2-4 parts of maleic anhydride grafted ethylene-vinyl acetate copolymer, 5-6 parts of melamine borate, 5-7 parts of polyethylene wax, 3-4 parts of copper naphthenate, 3-5 parts of diphenylmethane diisocyanate, 2-4 parts of isophorone diisocyanate, 2-3 parts of magnesium oxide, 4-6 parts of butyl phenolformaldehyde resin and 8-12 parts of filler. The formula and preparation method of the cable material are simple; the multiple fillers are added to enhance the light stability and chemical resistance of the cable material; and the cable material has favorable mechanical properties and wide economic prospects.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a light-stable cable material for high-power use and a preparation method thereof. Background technique [0002] With the development of my country's economy and the rapid development of the communication industry, more and more high-power equipment is used, which puts forward higher requirements for the performance of cables. The withstand power of the cable is linearly related to the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is limited by the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor, but at present Most of the cable materials on the market do not have excellent high temperature resistance and cannot meet the needs of current high-power equip...
